Philosopher, physicist, painter, and polyglot. At the age of 20, Camilla Ora is already all these things. And she’s eternally grateful to Caltech alumni—because, without their support, none of it would be possible.

Imagine you have been offered four options: You could have $10 million, $1 million, another year to live, or a chance to see someone you love. Your mental calculations will have a lot to do with your beliefs about your life. What if you expect to see someone you love tonight anyway? What if you think you have 70 more years to live? Or what if you are certain you have only 30 seconds?

When Caltech’s Nadia Lapusta creates computer models of earthquakes, she must integrate an astonishing range of data—on scales from thousands of kilometers down to microns and from millennia down to thousandths of a second. That’s because to understand the big and slow, she needs to understand the tiny and fast. “Large-scale earthquake ruptures—even those around 8 on the Richter scale—are ultimately happening in very narrow layers of granulated rock,” she says. In fact, where one side of a fault moves against the other, those layers are powdered so thin that a stack of a thousand grains would equal the thickness of a credit card. And although a fault can go eons between destructive quakes, the first slip that kicks off the shaking can take place in a blink.

Mars is Earth’s next-door neighbor, yet the Red Planet is utterly alien—frozen, arid, and roiled by massive dust storms. However, this was not always so. Data sent back from Mars, by JPL’s robotic explorers, paint the picture of two planets that once may have been much more similar. Woody Fischer, Caltech professor of geobiology, is helping to decode the history hidden in Mars’ rocky terrain.

They built bridges. Defused explosives. Defended freedom. For generations, Caltech alumni have served the United States. To commemorate Veterans Day, we share a few stories of alumni veterans’ military service, their years on campus, and their Caltech philanthropy.

Anneila Sargent (MS ’67, PhD ’78), Caltech’s Ira S. Bowen Professor of Astronomy, Emeritus, has made a gift to establish the Wallace L. W. Sargent Fellowship. With this fellowship, she is supporting tomorrow’s scientists and engineers while also honoring her late husband. Wallace “Wal” Sargent, former Ira S. Bowen Professor of Astronomy, served on the Caltech faculty from 1966 until his death in 2012.

“Caltech had the wherewithal to invest in the theory of relativity. It meant measuring the distance between two mirrors with a precision that is one-tenth the diameter of a nucleus. Any other place would have said, ‘This is insane.’ ”

“There is a Caltech way of doing science that provides a unique service to humanity. Break Through will ensure that Caltech can continue to accomplish things that other institutions are not able to do. ”

“Many physicists thought a quantum computer was a fantasy—impossibly error-prone. But at Caltech, we have freedom to do what we think is important. I got into the question of whether we could build one. In 1996, an idea from my particle physics background helped me find a way to fix errors. Now, people are realizing that method in the lab. And Caltech is setting the quantum agenda for the next 25 years.”
